i figured it would be because you become more dense. but i don't know that for a fact.

Haha holy.

It's possible that the voice change is unrelated. As a person ages, their larynx (voice box) may thicken. Producing less vibrations, and therefor a deeper voice. So even after puberty it is possible for ones voice to deepen.

However, is it a possibility that increased testosterone levels causes ones larynx to thicken? The changes in a boys larynx to a mans larynx is 'irreversible', and is primarily changed by sex hormones (androgens). So I wouldn't be surprised that it is directly related. Testosterone probably has some effect on collagen production, and if that collagen is deposited around the lamina in the larynx, then hypothetically, it is the 'cause'.

Causation does not imply correlation.

This is very interesting, thanks for the informative post.

Everyone else who responded seriously thankyou as well...

There could be a psychological reason but I haven't felt more "alpha" at all so I doubt it.

It may just be a randomn occurence like afranczyk stated

Either way it's impossible to know what caused it; still very intriguing to say the least

as far as voice changing during puberty, your voice really only 'settles' at the end of your teens/early twenties. you may have a deep voice during puberty, but it'll go up and down during your late teens. its like a curve. my guess would be that your taking t-bol just happened to coincide with your voice naturally deepening. you could up your test to levels off the chart and if your voice is tenor, it'll stay tenor. the pitch of your voice has NOTHING to do with testosterone, its the length of your vocal chords, so unless your vocal chords suddenly elongated...... Don't fear, its just your voice naturally settling.
